Creature Feature

Today’s Obscure Arcana focuses on four spells that do very similar things: augmenting creatures summoned by summon monster spells, allowing you to “mix-and-match” to build your own super-powered minions. Enjoy.

This spell may be cast as a free action as part of casting any spell of the summoning subschool which summons one or more creatures. Otherwise, the spell has no effect.

The summoned creature gains four primary tentacle attacks, which deal 1d4 points of damage each (for a Medium-sized creature). Further, the summoned creature gains the grab universal monster special ability, which applies to each of these tentacle attacks. If the summoned creature already possesses four or more tentacle attacks, then it does not gain these benefits, and instead its existing tentacle attacks deal damage as though the summoned creature were two size categories larger than it actually is.

These effects last for as long as the creature remains summoned. If more than one creature is summoned by the summoning spell that is cast in conjunction with Xybar’s aberrant summons, only one of the summoned creatures is affected.

The summoned creature is infused with negative energy and a hunger for the life force of living creatures. The summoned creature gains the lifesense universal monster ability. Additionally, each of the summoned creature’s natural attacks inflicts an additional 3d6 points of negative energy damage to living creatures (it has no effect on undead or creatures that are neither living nor dead). Finally, whenever the summoned creature inflicts negative energy damage with one of its natural attacks, it heals a number of hit points equal to 1/2 the amount of negative energy damage it inflicted (rounded down).

These effects last for as long as the creature remains summoned. If more than one creature is summoned by the summoning spell that is cast in conjunction with Xybar’s dark summons, only one of the summoned creatures is affected.

The summoned creature’s body is comprised of a gelatinous goo, instead of its normal composition. It is immune to precision-based damage and critical hits, due to a lack of true anatomy, and its fluid shape allows it to move through an area as small as one-quarter its space without squeezing, or one-eighth its space when squeezing.

This effect lasts for as long as the creature remains summoned. If more than one creature is summoned by the summoning spell that is cast in conjunction with Xybar’s gooey summons, only one of the summoned creatures is affected.

The summoned creature gains DR 2/epic; acid, cold, electricity, and fire resist 10; and regeneration 5. The summoned creature’s regeneration can only be overcome by damage from epic sources. Additionally, the summoned creature does not automatically depart when reduced to 0 hit points, as long as its regeneration is functioning.

These effects last for as long as the creature remains summoned. If more than one creature is summoned by the summoning spell that is cast in conjunction with Xybar’s unkillable summons, only one of the summoned creatures is affected.
